Abstract
PURPOSE We aimed to compare the diagnostic accuracy of perioperative ΔcfDNA to ΔCEA (over the first 2 years post-operatively) for identifying disease recurrence in colon cancer. METHODS Patients presenting for elective resection for colon cancer with curative intent were screened for inclusion. Perioperative cfDNA levels were measured at seven different times points(pre-operative and post-operative at 3 h, 6 h, 24 h, 48 h, POD3 and POD5). CEA levels were measured on the same patients up to 2 years post-operatively. Change in trend (Δ) was defined as the β coefficient using a logistic regression model. Statistical analysis was performed using SPSS, version 23. RESULTS Longitudinal data on twenty-two patients were analysed (n = 16 male, n = 6 female) for a median of 29 months (IQR 23 months) during which time three patients developed (distant) recurrence. Perioperative ΔcfDNA at 48Hrs, POD3 and POD5 were significantly associated with early recurrence. ΔCEA was significantly associated with early recurrence at 6 months, 1 year and 2 years post-operatively, only when disease recurrence was macroscopically established. ΔcfDNA was associated with an area under the curve (AUC) of 0.947 (95% CI 0.88-1.0, p < 0.001) and ΔCEA was associated with an AUC of 0.9382 (95%CI 0.88-0.99, p < 0.0001). This translated into a specificity of 97% (95%CI 86.51-99.87%) for ΔcfDNA and 77.5% sensitivity (95%CI 62.5-87.7%) in the immediate perioperative period and an 88.9% specificity (95%CI 56.5-99.4%) and 76.5% sensitivity (95%CI 63.24-86%) for ΔCEA over the first 2 years post-operatively. CONCLUSIONS In this pilot study, following curative resection for colon cancer changing trends in perioperative cfDNA (ΔcfDNA) identify those at risk of recurrent disease before recurrence develops which is at least 6 months earlier than CEA changes (ΔCEA) which are only observed when recurrence is established.

Abstract
OBJECTIVE Following a review of the existing body of literature, this study aimed to explore the need for a breast cancer awareness intervention specifically targeted at women with mild/moderate levels of intellectual disability (ID) and provide perspectives on the preferred processes and content underpinning an intervention. METHODS A qualitative, descriptive design using semi-structured, individual (n = 5) and focus group (n = 5) interviews were used to engage with a non-probability, purposive sample of key stakeholders (n = 25) including women with mild/moderate levels of ID, caregivers and healthcare professionals. Data were analysed using qualitative content analysis. RESULTS Findings highlighted that an educational intervention should focus on breast awareness as opposed to breast cancer awareness. Additionally, findings identified that a combined breast awareness and healthy living intervention could be effective. However, the intervention needs to have a multimodal, hands-on, person-centred approach to learning which is underpinned by theory. Furthermore, integrating the caregivers and healthcare professionals into the intervention is recommended. CONCLUSION Findings from this study provide a foundation for developing and implementing a theoretically underpinned, multimodal, breast awareness and healthy living educational intervention for women with mild/moderate levels of ID.

Abstract
OBJECTIVE The aim of this study was to determine the efficacy of serogroup-specific bivalent fimbrial vaccines in the control and elimination of relatively mild (intermediate) forms of footrot in sheep flocks in NSW, there being some evidence that such forms are difficult to control. METHODS Four flocks of sheep with history of footrot of intermediate virulence were selected based on clinical and bacteriological diagnoses. Dichelobacter nodosus serogroups included in bivalent vaccines at each farm were based on on-farm serogroup-prevalence data. Two doses of bivalent vaccine were administered with a 4-week interval between doses. Repeated post-vaccination inspections of all feet of between 100 and 119 animals per mob were conducted and foot swabs were collected for bacteriological testing. Blood samples were collected from 10 to 24 individually identified animals per flock at each inspection to check for agglutinating antibody responses. RESULTS In the majority of animals, antibody levels for serogroups included in each vaccine were above the level believed to be required for protective immunity. Footrot disappeared on farm 1 prior to vaccination, but did not reappear postvaccination. Footrot was controlled but not eliminated on farms 2, 3, and 4, where the prevalence and severity of the disease and number of serogroups present were reduced. CONCLUSION Serogroup-specific bivalent vaccines can be effective at controlling footrot caused by intermediate strains of D. nodosus.

Abstract
IMPORTANCE Obesity, particularly visceral obesity and sarcopenia, are poor prognostic indicators in colon cancer. OBJECTIVES To explore the association between body composition profiles and 5-year colon cancer outcomes and delineate the associated underlying inflammatory processes. DESIGN, SETTING, AND PARTICIPANTS This multicenter translational cohort study included patients with nonmetastatic colon cancer who did not have underlying chronic inflammatory disorders and were not receiving anti-inflammatory drugs referred to tertiary cancer centers from 2009 to 2015. Preoperative acute phase proteins (white cell count, C-reactive protein, and albumin), cytokines (interleukin [IL]-1b, IL-2, IL-6, IL-10, interferon γ, and tumor necrosis factor α), vascular endothelial growth factor (VEGF), and cell surface receptor expression levels (CD11b and CD14) were measured. All patients underwent follow-up for at least 5 years. Data were analyzed in December 2020. EXPOSURE Nonmetastatic colon cancer. MAIN OUTCOMES AND MEASURES The associations of body composition profiles with 5-year cancer recurrence and disease-specific mortality were analyzed using Mantel Cox log-rank test and Kaplan-Meier curves. RESULTS A total of 28 patients were included (median [interquartile range] age, 67 [58-72] years; 22 [78.6%] men). Low skeletal muscle area (SMA) and high visceral to total fat ratio were associated with poor clinical and oncological outcomes, including increased 5-year recurrence (low SMA: hazard ratio [HR], 2.30 [95% CI, 1.41-2.89]; P = .04; high visceral to total fat ratio: HR, 5.78 [95% CI, 3.66-7.95]; P = .02). High visceral to total fat ratio was associated with increased 5-year disease-specific mortality (HR, 5.92 [95% CI, 4.04-8.00]; P = .02). Patients with low SMA who developed a cancer recurrence, compared with those who did not, had higher C-reactive protein (mean [SD], 31.24 [6.95] mg/dL vs 8.11 [0.58] mg/dL; P = .003), IL-6 (mean [SD], 1.93 [1.16] ng/mL vs 0.88 [0.14] ng/mL; P = .004), VEGF (mean [SD], 310.03 [122.66] ng/mL vs 176.12 [22.94] ng/mL; P = .007), and CD14 (mean [SD], 521.23 [302.02] ng/mL vs 322.07 [98.35] ng/mL; P = .03) expression and lower albumin (mean [SD], 3.8 [0.6] g/dL vs 43.50 [3.69] g/dL; P = .01), IL-2 (mean [SD], 0.45 [0.25] ng/mL vs 0.94 [0.43] ng/mL; P < .001), IL-10 (mean [SD], 8.15 [1.09] ng/mL vs 16.32 [4.43] ng/mL; P = .004), and interferon γ (mean [SD], 2.61 [1.36] ng/mL vs 14.87 [3.43] ng/mL; P = .02) levels. Patients with high visceral to total fat ratio who developed recurrence had higher levels of IL-6 (mean [SD], 5.26 [7.05] ng/mL vs 2.76 [3.11] ng/mL; P = .03) and tumor necrosis factor α (mean [SD], 5.74 [4.53] ng/mL vs 4.50 [1.99] ng/mL; P = .03). CONCLUSIONS AND RELEVANCE These findings suggest that low SMA and high visceral to total fat ratio were associated with worse colon cancer outcomes and with increased expression of proinflammatory cytokines and VEGF and inhibition of anti-inflammatory cytokines.

Abstract
BACKGROUND/AIM Adjuvant therapeutic options are limited for triple negative breast cancer (TNBC). Thus, we evaluated the cytotoxic effects of the newly synthesized antineoplastic agent 1,4,5-Oxathiazinane-4,4-dioxide (OTD) on TNBC cells as a potential cancer therapeutic strategy. MATERIALS AND METHODS TNBC primary BT-20 and metastatic MDA-MB-231 cell lines were treated with increasing concentrations of OTD for various time periods to assess cell viability. Cell necrosis, apoptosis, necroptosis, autophagy, and ROS generation were evaluated using assay kits or specific inhibitors. RESULTS Treatment with OTD resulted in a dose- and time-dependent cell death of TNBC BT-20 and MDA-MB-231 cells. OTD also dose-dependently arrested TNBC cell proliferation. Notably, treatment with OTD induced both necrosis and apoptosis of TNBC cells, while the pan-caspase inhibitor Z-VAD-FMK partially attenuated OTD-induced cell death. Importantly, abrogated OTD-induced cell death was observed in the presence of the ROS scavenger N-acetylcysteine (NAC), whereas enhanced OTD-induced cell death was observed after the addition of the glutathione synthesis inhibitor BSO, indicating OTD-induced killing of TNBC cells via a reactive oxygen species-dependent mechanism. CONCLUSION OTD is strongly cytotoxic to both primary and metastatic TNBC cells, possibly by inducing multiple cell death pathways.

Abstract
INTRODUCTION Incidence rates for developing breast cancer are similar for women regardless of intellectual ability. However, women with an intellectual disability present with advanced breast cancers, which often have a poor prognosis. METHOD A structured narrative review of the literature was performed to explore the concepts of breast awareness and breast cancer awareness and subsequently, identify barriers to breast cancer awareness encountered by women with an intellectual disability. RESULTS A total of 22 studies involving people with varying levels of intellectual disability informed this review. The barriers to breast cancer awareness encountered by women with an intellectual disability include: lack of their understanding, the role of the carer and literacy issues. CONCLUSION Identifying the barriers to breast cancer awareness for women with an intellectual disability will help to facilitate breast cancer awareness which has the potential to result in better long-term outcomes through an early diagnosis of breast cancer.

Abstract
BACKGROUND Women with an intellectual disability (ID) have a similar risk of developing breast cancer as women in the general population yet present with later stage breast cancers, which have poorer outcomes. AIM To identify whether there is a need to develop a breast cancer awareness intervention for women with an ID. METHODS Interventions aimed at increasing cancer awareness and breast cancer awareness for people with an ID were identified and critically appraised. RESULTS Five interventions to increase cancer awareness or breast cancer awareness in people with an ID were identified. CONCLUSION The review highlighted the paucity of theoretically underpinned breast cancer awareness interventions specifically aimed at women with an ID. Facilitating breast cancer awareness for women with an ID could potentially lead to earlier presentation of potential symptoms of breast cancer, earlier treatment, better prognosis and ultimately, improved survival. This article establishes that there is a need for an intervention underpinned by theory to increase breast cancer awareness in women with an ID.

Abstract
Background. Breast screening has decreased morbidity and mortality due to detection of early, non-palpable breast cancers. One of the challenges of performing breast-conserving surgery on non-palpable breast tumours is accurate localization of the cancer. We aimed to perform a feasibility study to examine the outcomes associated with the introduction of a novel radiofrequency identification system (RFID) called LOCalizer as an alternative to traditional wire-guided localization. Methods. Data were prospectively collected on all patients undergoing breast-conserving surgery using the LOCalizer RFID system in a regional cancer centre between July 2019 and March 2020. Patients had a RFID tag placed preoperatively and underwent surgical removal of the tag with the index lesion guided by a handheld LOCalizer probe. The primary aim was successful placement and retrieval of the RFID tag. Re-excision rates, specimen size, specimen weight, cancer subtype and complication rate were all recorded. Results. Sixty-nine patients aged between 50 and 69 years had a LOCalizer tag inserted between July 2019 and March 2020. Of these, 6 (8.7%) were diagnostic and 63 (91.3%) were therapeutic. There was no migration of RFID tags, and all tags were retrieved with the index lesion. The overall re-excision of margin rate was 17.4% (12/69). All re-excision of margins was due to positive radial margins. The overall complication rate was 1.4% with one grade 1 Clavien-Dindo morbidity. Conclusion. The LOCalizer RFID is an effective and safe wire-free localization method for non-palpable breast lesions.

Abstract
BACKGROUND Carriers of the BRCA1 and/or BRCA2 mutation incur a lifetime risk of up to 85 per cent for breast cancer, and between 20 and 40 per cent for ovarian cancer. Efforts to estimate the lifetime risk of developing colorectal cancer for BRCA mutation carriers have produced conflicting results. Consequently, there are no formal guidelines regarding the need for bowel screening for individuals with BRCA1 and/or BRCA2 mutations. This systematic review and meta-analysis determined the risk of colorectal cancer associated with BRCA carrier mutations. METHODS The primary outcome was incidence of colorectal cancer in BRCA mutation carriers. Secondary outcomes were the incidence in BRCA1 and BRCA2 carriers, Ashkenazi Jews, and age- and sex-matched cohorts. RESULTS Eleven studies were included in the review, with an overall population of 14 252 and 4831 colorectal cancers identified. Nine studies were included in the meta-analysis. There was no increase in colorectal cancer among patients carrying a BRCA mutation (odds ratio 1·03, 95 per cent c.i. 0·80 to 1·32; P = 0·82). After adjustment for Ashkenazi heritage, and age and sex estimates, there was no increased odds of developing colorectal cancer (with no heterogeneity, I2 = 0 per cent). CONCLUSION BRCA1 and/or BRCA2 mutation carriers are not at a higher risk of colorectal cancer.

Abstract
Abstract
Background
Axillary lymph node status remains a significant prognostic indicator in breast cancer. Here, the diagnostic accuracy of ultrasound-guided fine-needle aspiration (US-FNA) and ultrasound-guided core needle biopsy (US-CNB) in axillary staging was compared.
Methods
A comprehensive search was undertaken of all published studies comparing the diagnostic accuracy of US-CNB and US-FNA of axillary lymph nodes in breast cancer. Studies were included if raw data were available on the diagnostic performance of both US-FNA and US-CNB, and compared with final histology results. Relevant data were extracted from each study for systematic review. Meta-analysis was performed using a random-effects model. The pooled sensitivity and specificity of US-FNA and US-CNB were obtained using a bivariable model. Summary receiver operating characteristic (ROC) graphs were created to confirm diagnostic accuracy.
Results
Data on a total of 1353 patients from six studies met the inclusion criteria and were included in the final analysis. US-CNB was superior to US-FNA in diagnosing axillary nodal metastases: sensitivity 88 (95 per cent c.i. 84 to 91) versus 74 (70 to 78) per cent respectively. Both US-CNB and US-FNA had a high specificity of 100 per cent. Reported complication rates were significantly higher for US-CNB compared with US-FNA (7·1 versus 1·3 per cent; P < 0·001). Conversely, the requirement for repeat diagnostic procedures was significantly greater for US-FNA (4·0 versus 0·5 per cent; P < 0·001).
Conclusion
US-CNB is a superior diagnostic technique to US-FNA for axillary staging in breast cancer.

Abstract
BACKGROUND Cosmetic outcomes and scar lengths remain important considerations in breast cancer surgery. Suturing techniques should decrease scar tissue formation and provide good cosmetic results. The use of an accordion suturing technique may result in decreased surgical wound lengths and better cosmetic outcomes. We compared the outcomes of the accordion suturing technique with the standard suturing technique in breast cancer surgeries. MATERIALS AND METHODS Female patients undergoing wide local excision of breast cancers were randomised to undergo closure of their surgical wound by either the accordion or the non-accordion (standard) suturing techniques between the months of May and October 2015. Pre-closure and post-closure wound lengths were measured intra-operatively. The primary outcome was a reduction of the surgical wound length at 6 weeks. The secondary outcome was a composite of the absence of hypertrophic scar tissue formation and optimal cosmesis. RESULTS Thirty eligible women for wide local excision of breast tumours were randomly assigned to the accordion and non-accordion groups (15 accordion and 15 non-accordion). Seven women were excluded from the study because they underwent re-excision of margins for their breast tumours before the end of 6 weeks, and one woman was lost to follow-up. We therefore compared the outcomes of 12 women who underwent closure of their surgical wound by way of the accordion suturing technique to the outcomes of 10 women who underwent closure with the non-accordion (standard) suturing technique. The percentage reduction of wound length at 6 weeks was significantly greater in the accordion group than in the non-accordion group (M = 24.4, SD = 10.2 vs. M = 8.6, SD = 11.5, p = 0.0026). There was no significant difference in the cosmetic outcome between both groups using the James Quinn's wound evaluation score. CONCLUSION The accordion suturing technique was associated with a significant reduction in surgical wound lengths in breast conserving surgery at 6 weeks without compromising the cosmetic result.

Abstract
BACKGROUND The presence of extranodal extension (ENE) is well documented as a predictor of non-sentinel lymph node (NSLN) metastasis. The ACOSOG Z0011 trial (2011) concluded that patients who satisfy criteria including the absence of sentinel lymph node (SLN) ENE can forgo axillary clearance (AC). Currently there are no studies analysing the rate of ENE in NSLN metastasis in which the sentinel node was positive but had no ENE. Determining this incidence will help determine if current paradigms are resulting in residual ENE in NSLN metastasis by forgoing AC based on the Z0011 trial.. METHODS This study determined incidence of ENE at NSLN metastasis in patients with a positive SLN biopsy without ENE in 162 symptomatic breast cancer patients who underwent AC between 2009 and 2014 at Cork University Hospital Breast Cancer Service, a teaching hospital of University College Cork. RESULTS Of 965 sentinel node biopsies performed 251 were identified as SLN positive, 162 (64.5%) underwent further AC. Of the 162 patients, 56.8% (92/162) were positive for ENE at SLN, of these 57.6% (53/92) had NSLN metastasis versus 17.1% (12/70) in the ENE-negative group (χ2 test; P < 0.001). On adjusted analysis, ENE at the SLN was a significant predictor of NSLN metastasis (odds ratio [OR] 8.63; 95% confidence interval [CI] 3.26-22.86; P < 0.001). The incidence of NSLN-ENE in patients without SLN-ENE was 1/70 (1.4%) compared with 33.7% (31/92) in patients who had ENE at the SLN (χ2 test; P < 0.001). CONCLUSION ENE at the SLN is an independent predictor of NSLN involvement; its absence significantly reduces the likelihood of ENE in NSLN metastasis..

Abstract
BACKGROUND Neoadjuvant therapy (NAT) offers a unique opportunity to assess tumor response to systemic agents. However, a discrepancy may exist between the response of the primary tumor and involved nodes. We report on the frequency of response discordance after NAT in breast cancer. PATIENTS AND METHODS All consecutive node-positive patients receiving NAT in our department from 2009 to 2014 were identified. Patient demographics, and radiologic and pathologic features were tabulated. Tumor response was estimated by magnetic resonance imaging of the breast. Lymph node (LN) response was estimated from pathologic treatment response measurements. Statistical analysis was performed. RESULTS A total of 108 node-positive patients treated with NAT were eligible for inclusion. Median age was 51.73 years (range, 20-87 years). All patients underwent axillary clearance, and 62% underwent mastectomy. A 40% mean reduction in tumor size was observed. Statistically, a positive correlation between tumor and LN response after NAT was observed (Spearman correlation coefficient, r = 0.46, P < .001). Complete pathologic response was observed in 17 patients (15.7%). However, 21 patients experienced complete LN response, with only 81% of these patients (n = 17) experiencing a complete response in tumor also. A complete response was observed in tumor in 20 patients, and this predicted complete nodal response in 85% of cases (n = 17). Fifteen percent of primary tumors with complete pathologic response had persistently positive LNs. CONCLUSION A significant discordance exists between the primary tumor and LN response, representing a concern for the lack of response of occult regional or systemic metastases due to potential biologic heterogeneity.

Abstract
The optimal duration and treatment strategies involving adjuvant endocrine therapy in early breast cancer remained largely undetermined. As data emerge on the various modalities of treatment in both pre- and postmenopausal groups, debates, and discussions continue. Most studies to date focused on the 5-year duration of treatment consisting of mainly tamoxifen. The Arimidex, Tamoxifen, Alone or in Combination (ATAC) study demonstrated that anastrozole is superior to tamoxifen and has become the mainstream treatment in postmenopausal women with early breast cancer, although the duration was arbitrarily set for 5 years, analogous to tamoxifen treatment. Several clinical trials, however, have emerged to support extended endocrine therapy as it becomes clear that the recurrence risk of breast cancer does not decrease beyond the initial 5 years of treatment. The advent of molecular signatures also plays an important role in the breast cancer profiling, and where available should be incorporated in the overall decision-making. Furthermore, side effects and noncompliance pose another issue in achieving an optimal treatment benefit. The decision-making as regards to extended endocrine treatment should therefore focus not only on the cancer biology alone but also include treatment side effects, assessment of risk of recurrence and patients' preference. In this review, we present an overview of the published studies to date as well as ongoing studies on the topic to better refine the options for adjuvant hormonal therapy.

Abstract
BACKGROUND Breast cancer continues to be the most commonly diagnosed cancer in women globally. Early detection, diagnosis and treatment of breast cancer are key to better outcomes. Since many women will discover a breast cancer symptom themselves, it is important that they are breast cancer aware i.e. have the knowledge, skills and confidence to detect breast changes and present promptly to a healthcare professional. OBJECTIVES To assess the effectiveness of interventions for raising breast cancer awareness in women. SEARCH METHODS We searched the Cochrane Breast Cancer Group's Specialised Register (searched 25 January 2016), Cochrane Central Register of Controlled Trials (CENTRAL; 2015, Issue 12) in the Cochrane Library (searched 27 January 2016), MEDLINE OvidSP (2008 to 27 January 2016), Embase (Embase.com, 2008 to 27 January 2016), the World Health Organization's International Clinical Trials Registry Platform (ICTRP) search portal and ClinicalTrials.gov (searched 27 Feburary 2016). We also searched the reference lists of identified articles and reviews and the grey literature for conference proceedings and published abstracts. No language restriction was applied. SELECTION CRITERIA Randomised controlled trials (RCTs) focusing on interventions for raising women's breast cancer awareness i.e. knowledge of potential breast cancer symptoms/changes and the confidence to look at and feel their breasts, using any means of delivery, i.e. one-to-one/group/mass media campaign(s). DATA COLLECTION AND ANALYSIS Two authors selected studies, independently extracted data and assessed risk of bias. We reported the odds ratio (OR) and 95% confidence intervals (CIs) for dichotomous outcomes and mean difference (MD) and standard deviation (SD) for continuous outcomes. Since it was not possible to combine data from included studies due to their heterogeneity, we present a narrative synthesis. We assessed the quality of evidence using GRADE methods. MAIN RESULTS We included two RCTs involving 997 women: one RCT (867 women) randomised women to receive either a written booklet and usual care (intervention group 1), a written booklet and usual care plus a verbal interaction with a radiographer or research psychologist (intervention group 2) or usual care (control group); and the second RCT (130 women) randomised women to either an educational programme (three sessions of 60 to 90 minutes) or no intervention (control group). Knowledge of breast cancer symptomsIn the first study, knowledge of non-lump symptoms increased in intervention group 1 compared to the control group at two years postintervention, but not significantly (OR 1.1, 95% CI 0.7 to 1.6; P = 0.66; 449 women; moderate-quality evidence). Similarly, at two years postintervention, knowledge of symptoms increased in the intervention group 2 compared to the control group but not significantly (OR 1.4, 95% CI 0.9 to 2.1; P = 0.11; 434 women; moderate-quality evidence). In the second study, women's awareness of breast cancer symptoms had increased one month post intervention in the educational group (MD 3.45, SD 5.11; 65 women; low-quality evidence) compared to the control group (MD -0.68, SD 5.93; 65 women; P < 0.001), where there was a decrease in awareness. Knowledge of age-related riskIn the first study, women's knowledge of age-related risk of breast cancer increased, but not significantly, in intervention group 1 compared to control at two years postintervention (OR 1.8; 95% CI 0.9 to 3.5; P < 0.08; 447 women; moderate-quality evidence). Women's knowledge of risk increased significantly in intervention group 2 compared to control at two years postintervention (OR 4.8, 95% CI 2.6 to 9.0; P < 0.001; 431 women; moderate-quality evidence). In the second study, women's perceived susceptibility (how at risk they considered themselves) to breast cancer had increased significantly one month post intervention in the educational group (MD 1.31, SD 3.57; 65 women; low-quality evidence) compared to the control group (MD -0.55, SD 3.31; 65 women; P = 0.005), where a decrease in perceived susceptibility was noted. Frequency of Breast CheckingIn the first study, no significant change was noted for intervention group 1 compared to control at two years postintervention (OR 1.1, 95% CI 0.8 to 1.6; P = 0.54; 457 women; moderate-quality evidence). Monthly breast checking increased, but not significantly, in intervention group 2 compared to control at two years postintervention (OR 1.3, 95% CI 0.9 to 1.9; P = 0.14; 445 women; moderate-quality evidence). In the second study, women's breast cancer preventive behaviours increased significantly one month post intervention in the educational group (MD 1.21, SD 2.54; 65 women; low-quality evidence) compared to the control group (MD 0.15, SD 2.94; 65 women; P < 0.045). Breast Cancer AwarenessWomen's overall breast cancer awareness did not change in intervention group 1 compared to control at two years postintervention (OR 1.8, 95% CI 0.6 to 5.30; P = 0.32; 435 women; moderate-quality evidence) while overall awareness increased in the intervention group 2 compared to control at two years postintervention (OR 8.1, 95% CI 2.7 to 25.0; P < 0.001; 420 women; moderate-quality evidence). In the second study, there was a significant increase in scores on the Health Belief Model (that included the constructs of awareness and perceived susceptibility) at one month postintervention in the educational group (mean 1.21, SD 2.54; 65 women) compared to the control group (mean 0.15, SD 2.94; 65 women; P = 0.045).Neither study reported outcomes relating to motivation to check their breasts, confidence to seek help, time from breast symptom discovery to presentation to a healthcare professional, intentions to seek help, quality of life, adverse effects of the interventions, stages of breast cancer, survival estimates or breast cancer mortality rates. AUTHORS' CONCLUSIONS Based on the results of two RCTs, a brief intervention has the potential to increase women's breast cancer awareness. However, findings of this review should be interpreted with caution, as GRADE assessment identified moderate-quality evidence in only one of the two studies reviewed. In addition, the included trials were heterogeneous in terms of the interventions, population studied and outcomes measured. Therefore, current evidence cannot be generalised to the wider context. Further studies including larger samples, validated outcome measures and longitudinal approaches are warranted.

Abstract
BACKGROUND Informed consent is an essential component of medical practice, and especially so in procedural based specialties which entail varying degrees of risk. Breast cancer is one of the most common cancers in women, and as such is the focus of extensive research and significant media attention. Despite this, considerable misperception exists regarding the risk of developing breast cancer. AIMS This study aims to examine the accuracy of risk perception of women attending a breast cancer family history clinic, and to explore the relationship between risk perception accuracy and health literacy. METHODS A cross-sectional study of women attending a breast cancer family history clinic (n = 86) was carried out, consisting of a patient survey and a validated health literacy assessment. Patients' perception of personal and population breast cancer risk was compared to actual risk as calculated by a validated risk assessment tool. RESULTS Significant discordance between real and perceived risks was observed. The majority (83.7%) of women overestimated their personal lifetime risk of developing breast cancer, as well as that of other women of the same age (89.5%). Health literacy was considered potentially inadequate in 37.2% of patients; there was a correlation between low health literacy and increased risk perception inaccuracy across both personal ten-year (rs = 0.224, p = 0.039) and general ten-year population estimations. (rs = 0.267, p = 0.013). CONCLUSION Inaccuracy in risk perception is highly prevalent in women attending a breast cancer family history clinic. Health literacy inadequacy is significantly associated with this inaccuracy.

Abstract
BACKGROUND The diagnosis and management of lobular neoplasia (LN) including lobular carcinoma in situ (LCIS) and atypical lobular hyperplasia (ALH) remains controversial. Current management options after a core needle biopsy (CNB) with lobular neoplasia (LN) incorporating both ALH and LCIS include excision biopsy or careful clinical and radiologic follow up. METHODS A retrospective analysis of the surgical database at Cork University Hospital was performed to identify all core needle biopsies from January 1st 2010 to 31st December 2013 with a diagnosis of FA who subsequently underwent surgical excision biopsy. All cases with associated LN including ALH and classical LCIS were selected. We excluded cases with coexistent ductal carcinoma in situ (DCIS), invasive carcinoma, LN associated with necrosis, pleomorphic lobular carcinoma in situ (PLCIS) or lesions which would require excision in their own right (papilloma, radial scar, atypical ductal hyperplasia (ADH) or flat epithelial atypia (FEA)). Cases in which the radiologic targeted mass was discordant with a diagnosis of FA were also excluded. RESULTS 2878 consecutive CNB with a diagnosis of FA were identified. 25 cases had a diagnosis of concomitant ALH or classical LCIS. Our study cohort consisted of 21 women with a mean age 53 years (age range 41-70 years). The core biopsy diagnosis was of LCIS and FA in 16 cases and ALH and FA in 5 cases. On excision biopsy, a FA was confirmed in all 21 cases. In addition to the FA, residual LCIS was present in 14 cases with residual ALH in 2 cases. One of the twenty-one cases (4.8%) was upgraded to invasive ductal carcinoma on excision.

Abstract
OBJECTIVES The information needs of cancer patients are highly variable. Literature suggests an improved ability to modulate personalised stress, increased patient involvement with decision making, greater satisfaction with treatment choices and reduced anxiety levels in cancer patients who have access to information. The aim of this project was to evaluate the effects of a mobile information application on anxiety levels of patients undergoing surgery for breast cancer. MATERIALS AND METHODS An application was developed for use with Apple iPad containing information on basic breast cancer biology, different treatments used and surgical techniques. Content and face validity studies were performed. A randomized control trial was designed, with a 1:2 allocation. Data collected include basic demographics and type of surgery. Questionnaires used included: the HADS, Mini-MAC, information technology familiarity and information satisfaction. RESULTS A total of 39 women participated. 13 women had access to an iPad containing additional information and 26 women acted as controls. The mean age was 54 and technology familiarity was similar among both groups. Anxiety and depression scores at seven days were significantly lower in control patients without access to the additional information provided by the mobile application (p = 0.022 and 0.029 respectively). CONCLUSION Anxiety and depression in breast cancer patients is both multifactorial and significant, with anxiety levels directly correlating with reduced quality of life. Intuitively, information should improve anxiety levels, however, we have demonstrated that surgical patients with less information reported significantly lower anxiety. We advise the thorough testing and auditing of information initiatives before deployment.

Abstract
INTRODUCTION New media technologies (computers, mobile phones and the internet) have the potential to transform the healthcare information needs of patients with breast disease (Ferlay et al. in Eur J Cancer 49:1374-1403, 2013). However, patients' current level of use and their willingness to accept new media for education and communication remain unknown. METHODS This was a single-centre clinic-based prospective cross-sectional study. A previously developed instrument was modified, validated and tested on patients attending a symptomatic breast clinic. RESULTS The instrument was evaluated on 200 symptomatic breast patients. The commonest outlets for education were staff (95 %), leaflets (69 %) and websites (59 %). Websites are more likely to be consulted by younger patients (<47 years), and patients who were working, students or homemakers (p < 0.05). Patients rated usefulness of information media in this order: (1) print, (2) phone, (3) website, (4) email, (5) text and (6) apps. Patients who were new to the clinic were more likely to find text messaging and emailing useful (n < 0.05). Younger patients (<47 years) are more likely to find text messages, apps, websites and email useful (p < 0.05). Urban patients are more likely to find websites and email useful (p < 0.05). Patients with higher education were more likely to favour apps, websites and email (p < 0.05). Smartphone owners were significantly more likely to rate text messaging, apps, websites and email as useful media (p < 0.05). CONCLUSION This study demonstrates that new media technology use among breast patients is expanding as expected along generational trends. As such its' further integration into healthcare systems can potentially ameliorate patient education and communication.

Abstract
OBJECTIVES The purpose of this study was to determine the optimum number of cells that should be counted when scoring human epidermal growth factor receptor 2 (HER2) brightfield dual-color in situ hybridization (BDISH), including cases with HER2/chromosome 17 (Chr17) ratios in the 1.80 to 2.20 range. METHODS IN TOTAL, 131 cases of breast carcinoma with HER2 immunohistochemistry and BDISH were included. For cases with a HER2/Chr17 ratio of less than 1.80 or more than 2.20 (n = 115), BDISH scoring was performed for 60 cells using three tumor fields, and for cases with a HER2/Chr17 ratio of 1.80 to 2.20 (n = 16), scoring was performed for 120 cells using six tumor fields. Mean HER2/Chr17 ratio and HER2 copy number were calculated for cumulative cell counts. RESULTS The HER2 status as determined by the HER2/Chr17 ratio or HER2 copy number was unchanged following counting of additional cells in 100% of cases with ratio of less than 1.80 or more than 2.20. The HER2 status of two cases with ratios of 1.80 to 2.20 changed from positive to negative following counting of 120 cells. CONCLUSIONS Our findings support recommendations to score 20 nuclei in conjunction with careful assessment of immunohistochemistry and scan of the BDISH slide to identify areas of heterogeneity. Scoring of additional cells/fields is likely not of benefit and might be a disadvantage since the scorer moves out of the area of strongest signal.

Abstract
The successful prevention and treatment of cancer is dependent upon efficient and reliable communication between healthcare workers and patients. Advances in social media and mHealth platforms have provided new ways in which to enhance the sharing of cancer related information. Other benefits of embracing this technology include utilising its analytic capabilities which can process the vast quantity of information generated from genome exploration in a highly efficient manner. The aim of this review is to provide an overview of the rapidly evolving areas through which digital engagement is proving useful in the prevention and control of cancer.

Abstract
BACKGROUND Papillary lesions of the breast are a relatively rare, but heterogeneous group ranging from benign to atypical and malignant. Debate exists regarding the optimal management of these lesions. In the absence of more accurate risk-stratification models, traditional management guidelines recommend surgical excision, despite the majority of lesions proving benign. This study sought to determine the rate of malignancy in excised breast papillomas and to elucidate whether there exists a population in which surgical excision may be unnecessary. METHODS A multicenter international retrospective review of core biopsy diagnosed breast papillomas and papillary lesions was performed between 2009 and 2013, following institutional ethical approval. Patient demographics, histopathological, and radiological findings were recorded. All data was tabulated, and statistical analysis performed using Stata. RESULTS A total of 238 patients were included in the final analysis. The age profile of those with benign pathology was significantly younger than those with malignant pathology (p < 0.001). Atypia on core needle biopsy was significantly associated with a final pathological diagnosis of malignancy (OR = 2.73). The upgrade rate from benign core needle biopsy to malignancy on the final pathological sample was 14.4 %; however, only 3.7 % had invasive cancer. CONCLUSIONS This international dataset is one of the largest in the published literature relating to breast papillomas. The overall risk of malignancy is significantly associated with older age and the presence of atypia on core needle biopsy. It may be possible to stratify higher-risk patients according to age and core needle biopsy findings, thereby avoiding surgery on low-risk patients.

Abstract
BACKGROUND The splintering of general surgery into subspecialties in the past decade has brought into question the relevance of a continued emphasis on traditional general surgical training. With the majority of trainees now expressing a preference to subspecialise early, this study sought to identify if the requirement for proficiency in managing general surgical conditions has reduced over the past decade through comparison of general and specialty surgical admissions at a tertiary referral center. METHODS A cross-sectional review of all surgical admissions at Cork University Hospital was performed at three individual time points: 2002, 2007 & 2012. Basic demographic details of both elective & emergency admissions were tabulated & analysed. Categorisation of admissions into specialty relevant or general surgery was made using International guidelines. RESULTS 11,288 surgical admissions were recorded (2002:2773, 2007:3498 & 2012:5017), showing an increase of 81 % over the 10-year period. While growth in overall service provision was seen, the practice of general versus specialty relevant emergency surgery showed no statistically significant change in practice from 2002 to 2012 (p = 0.87). General surgery was mostly practiced in the emergency setting (84 % of all emergency admissions in 2012) with only 28 % elective admissions for general surgery. A reduction in length of stay was seen in both elective (3.62-2.58 bed days, p = 0.342) & emergency admissions (7.36-5.65, p = 0.026). CONCLUSIONS General surgical emergency work continues to constitute a major part of the specialists practice. These results emphasize the importance of general surgical training even for those trainees committed to sub-specialisation.

Abstract
OBJECTIVE The main aim of our study was to establish the prevalence of social networking accounts among a group of second-level students (aged 15-18 years), to determine whether they used privacy settings, and to examine their attitudes to various aspects of social media use in medicine. DESIGN A descriptive study design was employed. The questionnaire was constructed specifically to address the attitudes of students to social media. No similar suitable validated questionnaire could be identified. The questionnaire consisted of 20 questions with a mixture of open answer, yes/no, and Likert scale response options. PARTICIPANTS Participation was voluntary and anonymous. Second-level school children interested in studying medicine and aged between 15 and 18 years took part. SETTING An annual open day organized by the School of Medicine in University College Cork, Ireland, formed the setting. The day comprised a mixture of lectures, demonstrations, and practical sessions designed to give the students insight into life as a medical student. RESULTS A total of 96 students attended, and all were handed the questionnaires. Of them, 88 students completed the survey. Overall, 90.9% of students had Facebook accounts and 53% had Twitter accounts. Of those with social media accounts, 14.8% reported having no privacy settings. Most respondents felt that unprofessional behavior on social media sites should be a factor considered in admission to medical schools. CONCLUSIONS Serious consequences can result from lapses in best practice relating to social media behavior. Dedicated reflective learning modules need to be incorporated into undergraduate and postgraduate training programs as a matter of urgency.

Abstract
INTRODUCTION Clean surgical scrubs, surgical gowns and headgear are worn by operative teams to decrease bacterial contamination and lower surgical site infection (SSI) rates. METHODS A detailed review was undertaken of peer-reviewed publications and other sources of material in the English language over the last 50 years included. RESULTS Surgical scrubs should be clean and made of tightly woven material. Studies investigating single-use gowns and drapes versus reusable gowns report conflicting evidence. Double gloving may reduce SSI rates in procedures where no antibiotic prophylaxis was administered. Bacterial contamination of the operative field has been shown to be decreased by the wearing of surgical headgear by the operating team. CONCLUSIONS Further consideration and better trials are required to determine the impact of different theatre clothing on SSI rates.

Abstract
BACKGROUND Chronic ulcers affect roughly 60,000 Irish people, at a total cost of €600,000,000, or €10,000 per patient annually. By virtue of their chronicity, these ulcers also contribute a significant burden to tertiary outpatient vascular clinics. OBJECTIVE We propose utilizing mobile phone technology to decentralise care from tertiary centres to the community, improving efficiency and patient satisfaction, while maintaining patient safety. METHODS Bespoke mobile software was developed for Apples iPhone 4 platform. This allowed for the remote collection of patient images prospectively and their transmission with clinical queries, from the primary healthcare team to the tertiary centre. Training and iPhones were provided to five public health nurses in geographically remote areas of the region. Data were uploaded securely and user end software was developed allowing the review and manipulation of images, along with two way communication between the teams. Establishing reliability, patients were reviewed clinically as well as remotely, and concordance analysed. Qualitative data were collected through focus group discussion. RESULTS From October to December 2011 eight patients (61-83 yrs, mean 75.3 yrs) with chronic venous ulceration and their five public health nurses were recruited. Data were transmitted using 3 G, Edge, GPRS and WiFi, at a mean speed of 69.03 kps. Concordance was 100% for wound bed assessment, 80% for skin integrity/colour and 60% for exudate assessment. Focus group analysis explored the concept, practicalities and future applications of the system. CONCLUSIONS With an evolving national data network, the secure transmission of clinical images is a safe alternative to regular clinic appointments for patients with chronic venous ulceration. With further development, and packaged as a freely downloadable application, this has the potential to support the community care of chronic wounds.

Abstract
BACKGROUND Psychologists have previously demonstrated that information recall is context dependent. However, how this influences the way we deliver medical education is unclear. This study aimed to determine if changing the recall context from the learning context affects the ability of medical students to recall information. METHODS Using a free recall experimental model, fourteen medical student participants were administered audio lists of 30 words in two separate learning environments, a tutorial room and an operating theatre. They were then asked to recall the words in both environments. While in the operating theatre participants wore appropriate surgical clothing and assembled around an operating table. While in the tutorial room, participants dressed casually and were seated around a table. Students experienced the same duration (15 minutes) and disruption in both environments. RESULTS The mean recall score from the 28 tests performed in the same environment was 12.96 +/- 3.93 (mean, SD). The mean recall score from the 28 tests performed in an alternative environment to the learning episode was 13.5 +/- 5.31(mean, SD), indicating that changing the recall environment from the learning environment does not cause any statistical difference (p=0.58). The average recall score of participants who learned and recalled in the tutorial room was 13.0 +/- 3.84 (mean, SD). The average recall score of participants who learnt and recalled in the operating theatre was 12.92 +/- 4.18 (mean, SD), representing no significant difference between the two environments for learning (p=0.4792). CONCLUSIONS The results support the continued use of tutorial rooms and operating theatres as appropriate environments in which to teach medical students, with no significant difference in information recall seen either due to a same context effect or specific context effect.

Abstract
Obturator hernia is a rare pelvic hernia that occurs primarily in multiparous, elderly (>70 years of age), thin females. This case highlights the successful laparoscopic mesh repair of an incarcerated obturator hernia in an octogenarian. The authors report a case of an incarcerated obturator hernia in an elderly female with subsequent high-grade small bowel and its successful laparoscopic operative management. A review of the relevant literature was also performed following a search on the online literature databases such as PUBMED and EMBASE. Laparoscopic mesh repair of the incarcerated obturator hernia and an ipsilateral femoral hernia found incidentally was successfully performed. A review of the literature showed a significant burden of morbidity and mortality associated with obturator hernias. Laparoscopic mesh repair has been previously shown to be a safe therapeutic modality. Small bowel obstruction and leg pain in a thin elderly lady should arouse suspicion for an incarcerated obturator hernia. Laparoscopic management of an incarcerated obturator hernia is a feasible and safe therapeutic option.

Abstract
INTRODUCTION Traditionally, surgical education has been confined to operating and lecture theaters. Access to the World Wide Web and services, such as YouTube and iTunes has expanded enormously. Each week throughout Ireland, nonconsultant hospital doctors work hard to create presentations for surgical teaching. Once presented, these valuable presentations are often never used again. AIMS We aimed to compile surgical presentations online and establish a new online surgical education tool. We also sought to measure the effect of this educational tool on surgical presentation quality. METHODS Surgical presentations from Cork University Hospital and Beaumont Hospital presented between January 2010 and April 2011 were uploaded to http://www.pilgrimshospital.com/presentations. A YouTube channel and iTunes application were created. Web site hits were monitored. Quality of presentations was assessed by 4 independent senior surgical judges using a validated PowerPoint assessment form. Judges were randomly given 6 presentations; 3 presentations were pre-web site setup and 3 were post-web site setup. Once uploading commenced, presenters were informed. RESULTS A total of 89 presentations have been uploaded to date. This includes 55 cases, 17 journal club, and 17 short bullet presentations. This has been associated with 46,037 web site page views. Establishment of the web site was associated with a significant improvement in the quality of presentations. Mean scores for pre- and post-web site group were 6.2 vs 7.7 out of 9 respectively, p = 0.037. CONCLUSIONS This novel educational tool provides a unique method to enable surgical education become more accessible to trainees, while also improving the overall quality of surgical teaching PowerPoint presentations.

Abstract
Checklists have been shown to improve patient outcomes. Checklist use is seen in the pre-operative to post-operative phases of the patient pathway. An adhesive checklist was developed for ward rounds due to the positive impact it could have on improving patient safety. Over an eight day period data were collected from five consultant-led teams that were randomly selected from the surgical department and divided into sticker groups and control groups. Across the board percentage adherence to the Good Surgical Practice Guidelines (GSPG) was markedly higher in the sticker study group, 1186 (91%) in comparison with the control group 718 (55%). There was significant improvement of documentation across all areas measured. An adhesive checklist for ward round note taking is a simple and cost-effective way to improve documentation, communication, hand-over, and patient safety. Successfully implemented in a tertiary level centre in Dublin, Ireland it is easily transferable to other surgical departments globally.

Abstract
Surgical patients are at particular risk of healthcare-associated infection (HCAI) due to the presence of a surgical site leading to surgical site infection (SSI), and because of the need for intravascular access resulting in catheter-related bloodstream infection (CRBSI). A two-year initiative commenced with an initial audit of surgical practice; this was used to inform the development of a targeted educational initiative by surgeons specifically for surgical trainees. Parameters assessed during the initial audit and a further audit after the educational initiative were related to intra- and postoperative aspects of the prevention of SSIs, as well as care of peripheral venous catheters (PVCs) in surgical patients. The proportion of prophylactic antibiotics administered prior to incision across 360 operations increased from 30.0% to 59.1% (P<0.001). Surgical site dressings were observed in 234 patients, and a significant decrease was found in the percentage of dressings that were tampered with during the initial 48h after surgery (16.5% vs 6.2%, P=0.030). In total, 574 PVCs were assessed over the two-year period. Improvements were found in the proportion of unnecessary PVCs in situ (37.9% vs 24.4%, P<0.001), PVCs in situ for >72h (10.6% vs 3.1%, P<0.001) and PVCs covered with clean and intact dressings (87.3% vs 97.6%, P<0.001). Significant improvements in surgical practice were established for the prevention of SSI and CRBSI through a focused educational programme developed by and for surgeons. Potentially, other specific measures may also be warranted to achieve further improvements in infection prevention in surgical practice.

Abstract
The aim of this study was to observe the error rate in the consent process of a university hospital and to illicit the opinions of the consenting doctors on the process. A prospective observational review of theatre consent forms was performed along with an anonymous survey of non-consultant hospital doctors (NCHD's). No potential risks were documented in 95.3% of the 64 scrutinized consents and late alterations were required in 9%. Respondents to the NCHD survey estimated that they were unsure of the procedure or risks involved in an average of 29% of occasions. Interns admitted to being unsure of the details of the procedure in almost a third (32%) of cases, making them less well informed than their senior colleagues (p=0.024). This study highlights the difficulties encountered by consenting doctors, an issue which may lead to patient dissatisfaction, threaten the efficient running of a surgical unit and potentially expose its staff to avoidable litigation. It also recommends the use of multimedia adjuncts to facilitate both patient and doctor education in the consent process.

Abstract
INTRODUCTION Obtaining a place in an Irish medical school is extremely competitive, a situation mirrored in many other countries. We aimed to determine the factors influencing school students in deciding to study medicine in university. We further determined what level of interest exists in pursuing a surgical career after completion of medical school. METHODS The Royal College of Surgeons in Ireland hosts an annual "Introduction to Medicine" programme for senior school children. Attendees were surveyed using a Likert scale to examine the factors influencing the group in choosing to study medicine, and pursue surgery as their ultimate career choice. RESULTS A total of 128 completed the survey, giving a response rate of 100%. The opportunity to help others was most the most influential factors cited by students (97%). Males were significantly more likely to have an interest in a career in surgery rather than medicine (p = 0.003), and ranked "financial reward" (p = 0.036) as a more significant factors in influencing career choice than did females. CONCLUSIONS A clear understanding of these factors influencing our students in their career choices and a strategy of recruitment based on these is imperative in order to optimize recruitment of students most suited to working as doctors.

Abstract
Sleep deprivation is an established part of the working life for Non-Consultant Hospital Doctors (NCHDs) in Ireland. Concern exists about the effect of extended NCHD work hours. We utilised a Nintendo Wii to evaluate motor function of NCHDs both prior to their on-call shift and the day afterwards. Data was exported to SPSS ver. 15 for statistical analysis with p < 0.05 considered significant. A total of 72 NCHDs were invited to participate in this study. There was a 62.5% (45) rate of follow-up. Overall 27 (60%) NCHDs were on medical call, with 18 (40%) on surgical call. There was no statistically significant difference between NCHDs pre-and post-call motor assessment scores. The majority of study participants (75.5%, n = 34) had four or more hours sleep. On-call duty allows for a greater than anticipated amount of sleep per on-call shift and therefore has a negligible effect on the motor skills of medical staff.

Abstract
Introduction. Currently, 175 000 people are on outpatient waiting lists in Irish hospitals. Many clinic slots are taken by patients returning for routine review postoperatively. Methods. A Nokia mobile phone was used to send an outpatient text (OPT) to patients 2 weeks postdischarge. Patients replying that they were well were discharged. If no reply after 2 attempts was received, they were scheduled for the next outpatient clinic. Results. Overall, 55 patients were offered the service over a 4-month period. Of these, 74.5% of patients were discharged from follow-up using text message surveillance. Patients were surveyed regarding their perception of the surveillance model, with all respondents ranking OPT surveillance as their preferred method of follow-up. There was a 13.6% decrease in outpatient visits over the study period. In addition, 6 emergency department visits were also avoided. Conclusion. Text message surveillance decreases outpatient waiting times and increases quality of care.

Abstract
Compared with systemic antibiotic therapy, the topical or local delivery of an antibiotic has many potential advantages. However, local antibiotics at the surgical site have received very limited approval in any of the surgical prophylaxis consensus guidelines that we are aware of. A review of the literature was carried out through searches of peer-reviewed publications in PubMed in the English language over a 30 year period between January 1980 and May 2010. Both retrospective and prospective studies were included, as well as meta-analyses. With regard to defining 'topical' or 'local' antibiotic application, the application of an antibiotic solution to the surgical site intraoperatively or immediately post-operatively was included. A number of surgical procedures have been shown to significantly benefit from perioperative topical prophylaxis, e.g. joint arthroplasty, cataract surgery and, possibly, breast augmentation. In obese patients undergoing abdominal surgery, topical surgical prophylaxis is also proven to be beneficial. The selective use of topical antibiotics as surgical prophylaxis is justified for specific procedures, such as joint arthroplasty, cataract surgery and, possibly, breast augmentation. In selective cases, such as obese patients undergoing abdominal surgery, topical surgical prophylaxis is also proven to be beneficial. Apart from these specific indications, the evidence for use of topical antibiotics in surgery is lacking in conclusive randomized controlled trials.

Abstract
Following the implementation of the Fottrell report, entry to medical school in Ireland has undergone significant change. Medical school studentship is now awarded based on a combination of points obtained from the final examination of Irish secondary schools (the leaving certificate) combined with HPAT scores (Health Professions Admissions Test). The HPAT is designed to test a candidate's knowledge in several different fields including problem solving skills, logical and non verbal reasoning. A sample HPAT was administered to a test group composed of consultant surgeons, non consultant hospital doctors, and medical students. Statistical analysis was performed and no significant difference was found between the performances of the groups. This is surprising as it was expected that groups with greater experience at medical problem solving would have translated to higher scores. This exposes a flaw within the HPAT system and a potential weakness in the process of doctor selection.

Abstract
BACKGROUND The aim of this study was to analyze the factors that influence the advancement and the career choices of doctors and medical students. METHODS Using the combined databases of the iformix and surgent websites, 450 doctors and medical students were invited to complete an internet-based survey. Surgent (http://www.surgent.ie) and iformix (http://www.iformix.com) are two free internet services administered by the authors. Surgent is a medical educational website, while iformix facilitates the online submission of abstracts to surgical and medical conferences across Britain and Ireland. The combined database of these two websites is approximately 4500 entries. Four hundred and fifty users represented a 10% sample based on an expected 40%-45% response rate. This was anticipated to yield between 180 and 202 respondents, statistically sufficient to analyze the data. A detailed Likert scale assessed the importance of "academic," "clinical," and "lifestyle" factors in determining career choice and progression. Analysis included descriptive statistics and inferential testing. RESULTS Fifty percent (N = 222) of surveys were returned; 142 men and 78 women. Thirty-seven percent of respondents were Irish, 28% British, and 35% non-European. Fifteen percent were undergraduates, 4% interns, 12% had 2-4 years of clinical experience, while 69% had completed more than 4 years. Fifty-six percent had decided upon a career in general surgery. Overall, the most important factors for career choice were intellectual challenge (95%), academic opportunities (61%), and research opportunities(54%). Doctors with more than 4 years of experience deemed duration of training (p = 0.002), lifestyle during training (p = 0.02), and stress (0.005) as less important factors when considering career choice. Correlation analyses demonstrated that prestige (p = 0.002), patient relationships (p = 0.006), and advice from friends or family (p = 0.01) were more important influencing factors for interns. In terms of career advancement, 66% of non-Europeans considered family contacts important as opposed to 20% of British and 45% of Irish doctors (p < 0.001). In addition, 47% of females felt gender was important for career advancement as opposed to 31% of males (p = 0.01). CONCLUSIONS Academic and clinical factors play an important role in career choice. However, it is clear that lifestyle factors predominate in determining an individual's career decisions in surgery.

Abstract
OBJECTIVE The aim of this study was to review the outcome of sentinel lymph node biopsy (SLNB) in patients with melanoma and to delineate whether patients with nodular melanoma are more likely to develop nodal recurrence despite negative SLNB. METHODS Consecutive patients with cutaneous melanoma undergoing SLNB were identified from a departmental database between 1997 and 2005. Factors including demographic data, site, histological subtype, depth and outcome were examined. RESULTS Of 131 patients, 103 were node negative and eligible for study. The median age was 53 (16-82) years with 46 patients being male (45%) and 57 female (55%). Primary melanoma sites included lower limb (49; 48%), upper limb (29; 28%), head (12; 11%), trunk (7; 7%) and back (6; 6%). The median Breslow thickness was 2mm. Superficial spreading accounted for 43% of melanoma with nodular accounting for 42%. Median follow-up was 40 (3-90) months. Of 20 relapses, seven recurred in the same nodal basin, three were satellite recurrences, one recurred with both satellite and nodal lesions simultaneously, and nine experienced haematogenous spread. Of the eight patients who developed recurrence in the same nodal basin, four were of nodular histological subtype (p=NS). All of the three patients with satellite lesions had nodular melanoma histologically (p=0.02). When nodal and satellite recurrences were combined, eight of 11 were histologically nodular (p=0.01). CONCLUSIONS This study indicates that lymphatic recurrence occurs more often in SLNB negative patients with nodular melanoma. Further evaluation of the inclusion criteria for sentinel node biopsy is warranted.

Abstract
For reasons that are unclear, skin from various body sites has different permeability properties. We have used hydrophilic penetrants (water, ethanol, mannitol, and paraquat) to study the in vitro permeability of skin from marmoset (eight body sites), man, and rat. Skin structure (stratum corneum thickness and number of cell layers; epidermal and dermal thickness; number and area of hair follicle openings per mm2) was compared with permeability. There was no apparent relationship between skin structure and permeability to the most rapid penetrants, water and ethanol. Follicle area opening was the structural feature that varied most between species and between body sites. Different marmoset body sites showed a threefold range in follicle area but this did not appear to influence the absorption rates of the test penetrants. However, among the species there was an 80-times range in follicle area, which correlated with the observed differences in rate of mannitol and paraquat absorption. Thus, permeability could be related to inter-species differences in skin structure, but only with the relatively slowly absorbed test penetrants, mannitol and paraquat.
